The role of hypoxia-induced factor in the regulation of oxygen homeostasis during reparative regeneration in compromised microcirculation

Abstract

The aim of the present review is to find an answer to the clinically important question on the mechanisms regulating the activity of reparative regeneration in hypoxic conditions and potential ways to modify this process. In the recent studies, compensated hypoxia is characterized as a trigger for the regeneration, with the central regulating factor being the member of the cytokine family, hypoxia-inducible factor-1 (HIF-1). Changes in the concentration of this protein modulates cell migration, angiogenesis and epithelialmesenchymal integration; it also stimulates the proliferation of endothelial cells and fibroblasts, playing a major role in the stimulation of wound healing, especially with compromised microcirculation, for example, diabetes mellitus.
